Kite Altitude World Record
Hello, I'm Bob Moore.
I hope you find my website interesting.   It's our story obout our quest to break the world altitude record for a single kite.
October 2005 on Cable Downs The 2 big DT Delta kites are 16 sq meters and 120 sq meters. The green and yellow delta is 2.25 sq meters. A 1.75 sq metre delta (purple & red) and a 8 sq metre Scott Sled (pink) rests on the ground
10,466 ft
6,500 ft
3,250 ft
Since 2005, apart from 2006 and 2008, a small group of enthusiasts have made an annual trek to Cable Downs sheep station near Cobar in western NSW, Australia We have been flying big kites to high altitude. We are attempting to break the world altitude record for a single kite on one line. Our activities  have the protection of an aircraft free zone provided by the Civil Aviation Safety Authority (CASA) and Air Services Australia. So far we have flown a big Dunton - Taylor delta kite to 14,188ft above ground level. This is just 321 feet short of the claimed record. This record was submitted to Guinness by Canadian, Richard Synergy in the year 2000. He submitted a height of 13,609 ft above ground level to the kiting community soon after his attempt. Later he said he flew  to14,509 ft above ground level which is the altitude submitted to Guinness. I t seems there are many inconsistencies with his claim and the method he  used to measure altitude. Despite these doubts, our target remains at15,000 ft above ground level to clearly reset the record. We are permitted to fly up17,370 ft above ground level and to reach that height wouldbe "icing on the cake".
I would like to thank the people who have been involved, supported or shown interest in our record attempts including:
Michael Richards
Michael Jenkins
Roger Martin
Barry Coppenhall
Greg Moore
Hugh Moore
Steve and Karen Viant of Cable Downs for hosting the record attempts.
Robbie Buck of ABC 702 Local Radio
Nancy Shannahan of The Cobar Age
2DU radio
Daily Telegraph
David Horan - Australian Kiteflyers Society
DSM Dyneema for supplying line
Universal Instruments for the loan of theodolites
Lewis Pulleys for winch components
Dyneema®, the world’s strongest fiber™
Where eagles dare. A 2 meter eagle soars with the big DT Delta in October 2005 at 3,000 ft above the air strip.

Hugh and Greg Moore recovering line at the western end of the Cable Downs air strip October 2005. The kite had gone down after the electric winch motor burned out.  During attempts to "walk the line down" a splice had separated with 2 km of line still attached. The line end then had caught in a tree keeping the kite flying  at about 3,000 ft.  The kite eventually came down on a property to the east, laying line over the tree tops. We recovered the line without much difficulty but it was effectively the end of our record attempts for 2005.
Glossary

AGL:
Above ground level. The kite's altitude must be measured from the altitude of the launch point. The sea level (AMSL) altitude is the reference for GPS units then the ground height above    sea level is subtracted from AMSL to give height above the launch point.
AMSL: Above Mean Sea Level. The reference height for GPS and land survey.
ISA air density: The standard  worldwide air density at sea level at 20 deg C and 50% humidity. 1013.5 Mb of pressure.
Lapse rate: The rate at which air density drops with altitude. A standard value at ISA standard temperature and pressure, 2.6% per 1,000 ft of altitude.
Isobar: In meteorology, Lines on a map joining points of equal air pressure. The general reference for for wind flow direction.
Catenary: The curve of a chain suspended at both ends under gravity. The approximate curve a kiteline assumes without the effect of wind, i.e. an unequal hieght catenary.
Kite Drag: The wind force that pulls the kite parallel to the ground. Combined with kite liftthe resultant force produces line tension and kite flying angle.
Kite lift: The vertical force generated by air flowing against and over the kite. The magnitude is directly related to wind speed, angle of attack and kite type and lift area.
Line tension: Measured in lbs or kg and varies at the square of wind velocity. Doubling the wind speed at the kite quadruples the line tension. Line tension is a product of kite drag, kite lift and line drag.
Dyneema: An very high strength synthetic fibre, made from ultra high molecular weight polyethylene (UHMWPE), that composes the kite line used for the record attempts. Made by DSM in Holland, the fibre is braided into our kite line by Cousin-Trestec in France.
Spectra: Similar to Dyneema fibre but made under licence from DSM by Honeywell in the USA and line manufactured from this fibre by various manufacturers such as Innotex, USA.
GPS: Global Positioning System. A system of 24 satellites positioned in orbit above the earth that transmit signals to enable very accurate location of people objects and their velocities.
Telemetry: Literally, transmission of measurements. Any system that uses radio signals to transmit data between 2 points. GPS telemetry is used on the kite to transmit GPS positional data from the kite to the ground.
